Buderus flat panel radiator problem.
Hi All–I have several Buderus panel model 22 radiators, and I love them. I have a problem with one, however. It’s 2′ x 6′ and heats my main living area. The problem is that only about the first foot (or less) of the panel actually heats up. I have a thermostatic control head on each of the panels, and have the flowsetter valve set to “N” per the instructions, which seem to work with my other panels just fine. I’ve monkeyed with the flowsetter valve on the problematic panel in various ways. When I turn the valve to a position between N and 7, I can hear water flowing into the panel, but it doesn’t seem to matter. I’ve left the thermostatic head off the panel for several hours, and tried the valve in various positions (N, 7 and so forth). No change. I’m fresh out of ideas. Can anyone out there make any suggestions? I’m tired of using a space heater in that are of my house! Thanks–john

did you contact your supplier?

Unfortunately, I don't know who the supplier was (Long story short is that the general contractor who subbed out a lot of the work on my house has been stripped of his license and is being hit with several lawsuits. I got lucky, but sometimes even recommendations don't turn out well :). I thought that before I called in another local supplier/expert, I'd see if there's something stupid I'm doing or not doing with the rad. Thanks! john

In that case I'd get on the phone with Buderus and see if customer service might be of some help. There is a possibility that there's someone familiar with this type of radiant, sorry I don't know squat.
Best of luck.
Sounds like an air lock.
Bleedin' air lock! Thanks.
Well, it turns out DanH was right. Bleeding the radiator fixed the problem in about 30 seconds. Thanks for the advice and help. The only downside is that I've been suffering with this silly problem for several months. *sigh*
thanks again, gentlemen!

If you don't already have a manual..........
get one from Buderus-There's usually some information that you can use in those things. Might save you some headaches down the line.
For example
here's one-
http://www.buderus.us/files/201007122124230.Panel_radiator_design_manual_12.2009.pdf
I browsed through it, found bleeder valve mentioned but no real use guide in here on that-
however, there was design info that might help you with the settings. Just fiddling around with a system is not the way to go.
1st rad in a series needs to be full open-so all the remaining get full flow, and then some tempering can be done-which evidently does affect those rad's downstream-so proper balancing needs to be considered.
Like I said, quick skim on the reading-you check it out, might make sense to a user.
